A potential client is running Profit21 on AIX. I resurrected my RS6000 PowerServer 520H (hadn't been powered
up in about a year) and connected an external 4mm tape drive to the SCSI chain. The machine already has an
8mm internal tape but the client only has 4mm. I dumped a test file from his system to a 4mm cartridge and
tried reading it when the 4mm was attached to a Linux machine here, did't work. I thought perhaps it was a
compatability issue with tar so I connected the drive to the RS6000. I tried using SMIT to define another
tape drive (I guess it would be RMT1 or RMT0.1?). With Linux you can go to the /proc/scsi directory and see
what devices were recognized by the system (example below). Since all attempts with SMIT failed is there an
easy way to find out what address the 4mm has with AIX or is there a similar directory where AIX catalogs
device information?


[root@softtail root]# cd /proc/scsi
[root@softtail scsi]# ls
aic7xxx scsi sym53c8xx
[root@softtail scsi]# cat scsi

Hi,

In order to configure a new SCSI device tou must fisrt check if it's SCSI ID
isn't already use by another device.
SCSI tape Drive is usualy ste to ID 5 by manufacturer.
Change your SCSI ID on the 4mm tape drive.
launch the followinfg command : cfgmgr -v
After you can check your new SCSI drive state with : lsdev -Cc tape

Andre, thanks for the reply. I've tried these commands with the 4mm drive on SCSI IDs 0 on up. Each time I
cold start the box after changing the ID with everything powered off. Cfgmgr -v shows scsi0 and the tape on
the 4mm spins for a while but it never is added to the system. I know the tape drive works, I had it running
on my Linux box. Any other ideas?

Hi,

You won't use ID 0. Try with another one.

Andre, I tried 0 through 6 (that's what I meant by "on up"). Is ID 0 the address on a MCA machine where ID 7
is used on ISA / PCI?

The AIX equivalent is 'lscfg -C'

I've remeber having to change dip-switches on the 4mm drive to make it
work between PC's and RS6000.

If the 4mm DAT tape drive is a HP SureStore then go to HP:s support for
information on how to set a couple of small switchen on the underside of the
tapedevice (you might have to take the cover of the device to reach the
switches).

Nope, HA ID is 7 like on x86 boxen. 0 should workas well,
but has the lowest priority on the bus.
(Thats why IBMs MCA PC boxen used to boot ID6.)

Using smit go to "add devices after IPL" and let it detect your drive
Other Choice is "devices" "tape" add "ost" there and copy the settings
from the IBM 4mm drive.
Make sure your cabling is working properly.
Run "diags" to make sure the drive is detected by the machine.
The noise it makes after power up is the usual selftest,
not initiated by the host machine, but the device itself.

Ran into trouble myself lately while adding a non IBM
(but detected as IBM) Tandberg QIC which frequently failed
mode select command due to its non IBM Firmware?
Some non IBM drives bevave picky on blue HW.

Gereon, thanks for the suggestion. I went via SMIT and used the add devices after IPL. While that was
running the 4mm tape drive was spinning. When it completed the 4mm drive stopped. Unfortunately SMIT came
back saying OK but below it said
cfgmgr: 0514-609 Unable to save the base customized information on /dev/ipldevice.


I also tried the ost option. It asked for location and I entered the SCSI ID as 30 where 3 is the ID and 0
the LUN. It didn't like that producing the error:
Method error (/etc/methods/cfgsctape):
0514-044 Cannot make a special file.

I tried the help options but still can't figure it out. I guess it is time to rip the 520H and 4mm drives
apart to see if there is an open position on the SCSI cable to temporarily connect the tape or substitute it
for the 8mm device.

Suggestions?
